Only to make things clear when I say evaluation that is not dependent only on
the leaf position I do not mean to root processors that change their static
evaluation when the root position is changed.

I mean that the same position may be evaluated different in the same search.

An example is to have evaluation closer to a draw if you suspect perpetual check
based on the fact that the inferior side gave many checks.

You can get the same position also without many checks and in this case my
evaluation is different.
